Type /tmw and change the auras I have with what you want. By right clicking on the icons, you will be able to open the menu and change it. I think it's one of the easiest addon to use so you shouldn't have any problem at all..
For other tmw's changes such as : add group, show only in combat, etc... go on the interface menu.

I don't know, this is really weird. Make sure that all the sldt addons are enabled, if yes, I don't really know how you can fix it. Just disable it I guess and in the future I'll try to fix it. Thanks for the feedbacks btw.

This is how it should look like after typing /sldt global. If it doesn't work I don't know, it's really weird to be honest. Let me know if you managed to fix it.
This is the other menu for names above npcs, characters etc...

You need to change fonter's profile to SpeedtixUI and your issue with names should be solved. In case it doesn't work you can try to go on normal interface menu, names, and then check if something is messed there. If nothing of what I said works, just type your issue on google and try to fix from there :)
About the other issue yo...
